Abstract

Abstract:

The findings of this study reveal that a species（Petrocosmea condorensis Pellegr.）， described in Petrocosmea one hundred years ago， in fact represents an independent genus in Gesneriaceae. This species is characterized by a flat-faced corolla， suborbicular leaf blades， linear filaments， and conical-ovoid capsules dehiscing into two valves， exhibiting a series of unique morphological characters. Molecular phylogenetic analyses demonstrated that this species belonged to the subtribe Loxocarpinae（Tribe Trichosporeae） within the subfamily Didymocarpoideae of Gesneriaceae and is sister to a clade comprising several other genera. Based on morphological and molecular phylogenetic evidence， we here elevated this species to a new genus， Zhenyuenes， with the establishment of a new combination.

Key words: Vietnam, new genus, new combination, Zhenyuenes, Gesneriaceae
